Answer:11 cm
Step-by-step explanation:
Formula to get perimeter is = side × 4
Take side as = x
Equation is = x × 4= 44
X= 44÷ 4
X= 11
Answer = 11cm
Answer: 47 feet
Step-by-step explanation:
Originally the scuba driver was 31 feet below the surface of the water.
She then dives down a further 16 feet. The depth below the surface is now:
= 31 + 16
= 47 feet
The Scuba driver is now 47 feet below the surface of the water so if she had to come back to the surface, she would have to rise that 47 feet to get to the surface.
C = 2pi*r
Plug in the circumference
6.28 = 2*pi*r
3.14 = pi *r
plug in pi
3.14 = 3.14 * r
r = 1
On her map 1 inch is equal to 20 miles.
5x=100
divide both sides by 5
x=20
5 is for the 5 inches.
x is for the unknown.
100 is the 100 miles between the cities.
So the scale 1:20
